Hello,
I am following the instruction of creating FB - the FlipFlop as BFB instructions.
I got 2 problems:
1. The Null State (Inital state) cannot add the action
2. I change the algorithm to as similar as BOOL2BOOL function block. However when I test by FBTester, it doesn't work (So nothing in the output). The BOOL2BOOL work quite well.

Could you please tell me the correct way to make a FB ?.
Thank you so much,

ad 1) according to IEC 61499-1 the initial state of an ECC must not have actions.
ad 2) did you export your new FB and recompiled FORTE as described in the tutorial? Are you starting your selfcompiled FORTE?
